rockpi and raspberrypi. #37

Closed rottnest closed 1 year ago

rottnest commented 1 year ago

Hi I've got a year old and a week old rockpi 4A (2G on the old, 4G on the new) Both display no action at boot.

I made a card for a 4G raspberry pi 4. It boots, I see 'scripts' in the messages then the display goes blank. It is a 1080 display that does work from 768x1024. The blue led flashes in regular pairs of flashes.

I downloaded src.tgz and will try to build

I've said more on the mythtv-users list

James, I see you are using RockPi 4A. Image I’m building is for RockPi 4B and for sure it will not work on Your board without change device tree(*) file Now DT is for RockPi 4B while Your board requires DT for RockPi 4A. So pls copy+rename boot/dtbs/rockchip/rk3399-rock-pi-4a.dtb file to /boot partition named as rk3399_dtb

Regarding RPI4: May you pls provide me MiniMyth2 Diagnostic Info content? It is in /var/log/system-info Alternatively in browser TopMenu/Logs/MiniMyth2 Diagnostic Info

Piotr I’m not trying to give you a hard time - promise :-) I’ve played with lots of things, just not ARM so I’m pretty much completely naive !

Because ra-pi gives no display, I mounted the SD card elsewhere to get the logs you asked for and while playing around after 2nd reboot MiniMyth is playing !

Now to play with the rockpi. There is NO board support package on your release, I got one elsewhere and will play with it. Cheers James

James,

let me explain how things are going here:

my distro (minimyth2) has rk3399 u-boot (bootloader) built with rock-pi-4-rk3399_defconfig. IIRC this config should cover all rockpi 4 boards.

minimyth2 boot script (boot.scr) is prepared for rockpi-4b (uses dtbs/rockchip/rk3399-rock-pi-4b.dtb)

for cases like yours (board is different than declared in boot.scr) - I developed solution where user can add custom DT. This procedure is programmed in boot.scr and is based on logic like this:

1.look for rk3399_dtb is /boot 2.if present - use it 3.if not present - use DT declared in boot.scr

So by putting rk3399_dtb into /boot - you will ask minimyth2 to use right DT for your bard (rk3399-rock-pi-4a.dtb)

pls do above and let me know how it goes

Thanks, better understanding. My error was assuming 4A is exactly like 4B without wifi n bluetooth. I made a card with rk3399.dtb from debian-buster, went for supper, and there it was - GONE. If hunting does not find then I'll craft another in the morning. How much ram do you need?

DTB is kernel version specific! Pls use right dtb file from my SD card.

So:

  1. flash SD card with image from my github repo

  2. mount r/w SD card boot partition

  3. copy file from this SD card: boot/dtbs/rockchip/rk3399-rock-pi-4a.dtb file to /boot partition root dir as rk3399_dtb (exact such name. no rk3399.dtb. it must be „rk3399_dtb”)

  4. unmout SD card

  5. insert in bard. it should boot.

Hi Piotr

I downloaded the image this morning. Mounted.

cp /mnt/rockchip/rk3399-rock-pi-4a.dtb rk3399_dtb

sync

Plugged in, power-on, nothing:

green led no blue activity

I’m going to try build from src. (native, not cross) what I am trying to see is if the display is smoother. My card I’m using is 2G, my 4G card has a m2 card. I’ve broken the m2 cable 3 times over the years so I’d rather not undo the m2 to mount an SD.

FYI I’ll keep you informend Cheers James

PS Jim Abernathy is using frame buffer on EGLS. That seems somwhat hard.

warpme commented 1 year ago

James, May you point me to exact URL with linux distro booting ok on your board?

btw: i think your cp command is simply wrong: 1.it is dependent on your's actual filesystem location at it's execution time - so it is highly prone to where you are in filesystem actually 2.no matter were you are in filesystem - absolute source path is WRONG

Assuming SD card is boot part is mounted on /mnt

command should be: cp /mnt/dtbs/rockchip/rk3399-rock-pi-4a.dtb /mnt/rk3399_dtb

Full procedure on Ubuntu: -insert SD Card do following commands:

mkdir /mnt/boot
mount /dev/sdX /mnt/boot/
cp /mnt/boot/dtbs/rockchip/rk3399-rock-pi-4a.dtb /mnt/boot/rk3399_dtb
ls /mnt/boot/

verify rk3399_dtb is present

sync
umount /mnt/boot/

remove card and insert into bard

ps: X is Linux device assigned to Your SD card

Hi

this boots and runs on ra-pi 4

MiniMyth2-armv8-32-12.6.2.r60-board-sm1.tanix_tx5_plus-board-rpi34.mainline64-SD-Image.img.xz

this does not boot

MiniMyth2-armv8-32-12.6.2.r60-board-rk3399.rockpi4-b-SD-Image.img.xz

I copied the dtbs/rockchip/rk3399-rock-pi-4a.dtb to rk3399_dtb

On power on: green led. The End. No blue led activity. No network presense.

The url is your git hub ie https://github.com/warpme/minimyth2/releases/download/v12.6.2-v32.0-60-ge5c974e402/MiniMyth2-armv8-32-12.6.2.r60-board-rk3399.rockpi4-b-SD-Image.img.xz

linux distro booting ok on your board - i was meant booting on rockpi4a - not on rpi4.... Also - may you - for now - experiment with most current mm2 image (v12.9.0)?

Piotr I do not know how to get omax support. I built 22 from src and the display performance is aweful The only reason I was looking at rockpi was to compare display. Do you have a rockpi, if so what is performance like?

The video he shows seems quite nice, but it's hard to tell https://www.explainingcomputers.com/rockpi4.html https://www.explainingcomputers.com/rockpi4.html

James,

I switch rockpi4 from mainline u-boot to radxa (producer of your's board) https://github.com/warpme/minimyth2/commit/8d9c9a190715d9224612816234582e2235480809 https://github.com/warpme/minimyth2/commit/0cbd91bcc1f6167e13e062e231dcb990fe47c947 https://github.com/warpme/minimyth2/commit/be347a3a21167cf1cf8b6a8c72bfabd879b12e6c. On mine rockpi-4b works perfect. Here is mage: https://github.com/warpme/minimyth2/releases/download/v12.9.0-v33-922-g61b82f2b5a/MiniMyth2-armv8-master-12.9.0.r933-board-rk3399.rockpi4-b-SD-Image.img.xz It should work on yours rockpi-4a. If not - try change device-tree like I advised here: https://github.com/warpme/minimyth2/issues/37#issuecomment-1296716529

re performance of rockpi4: mpeg2/h264/vp8/vp9/hevc - all are hardware accelerated. i have silky smooth playback - including 4k@60fps hevc playback of 4k@60fps gets 3..5% of cpu on mm2 on rk3399 - myth just flying

Yup that boots - thanks My main BE is 32, so I’m just building a master be to test with Cheers James

Poitr Hi

I am using 32 but built a master backend to test. The ‘master’ image I downloaded looks at, then plays my 32 backend !!! That suits me ideally, but I guess it is not what you want.

Side-by-side my evalution is

raspberrry pi 5/10 rockpi 7/10 intel + i3 8/10 mac 4xi5 8/10

I guess the limiting bit is OTA recording. They are pretty crappy doing 2-4 Mb/s (DVB) at 25 fps. but all in all, good and thanks lots for your help.

I’ve got the jellyfish egs. Just looked at those. Wow at 10 Mb/s I’d give the the rockpit 10/10. absolutly silkysmooth.

I should do the a/b again with good quality recordings OTH gonna be watch crappy OTA stuff James

warpme commented 1 year ago

James,

just 3 things before i will close this ticket:

  1. for sure you are using v4l2 video decoding profile right?
  2. you can periodically update mm2 to current most actual version over Internet. to do this you can:

option1: use option in GUI Setup/System Maintenance/System Updates/Check for updates (if you are using Default menu scheme) Advanced/Maintenance/System Updates/Check for updates (if you are using Media Centre menu scheme)

option2: log to device via telnet run mm_do_online_update to check are there any updates run mm_do_online_update doupdate to update then

sync
reboot
  1. if you found mm2 nice to use - pls put word about this in mythtv-users mailing list in topic where all this was initiated (Raspbery PI topic iirc)
